I've had to hit the books again to improve my understanding of variables, classes, and methods.
I've been re-writing my text adventure game so that every aspect of it is tested by the Rakefile. This means that I have had to extrapolate the logic of the enter() method in each class, so that a test can be written for it.
The most interesting parts of the game involve somewhat complex conditionals, written as case conditionals, and for some reason it took me a while to understand how to pass on a variable to the method containing a case conditional. Now that I look at it again, it's very simple, but c'est la vie.
Anyway, the re-written game is nearing completion and the latest code is up on Github.
